Lifitegrast (trade name Xiidra) is an FDA approved drug indicated for the treatment of signs and symptoms of dry eye, a syndrome called keratoconjunctivitis sicca. Lifitegrast reduces inflammation by inhibiting inflammatory cell binding. It is often used in conjunction with ciclosporin (Ikervis or Restasis) for dry eye treatment including meibomian gland dysfunction and inflammatory dry eye.
Lifitegrast is supplied as an eye drop and typically applied two times a day.
Mechanism of action
Lifitegrast inhibits an integrin, lymphocyte function-associated antigen 1 (LFA-1), from binding to intercellular adhesion molecule 1 (ICAM-1). This mechanism down-regulates inflammation mediated by T lymphocytes.
Lifitegrast was initially designed and developed by SARcode Bioscience which was acquired by Shire in 2013, who submitted a new drug application to the US Food and Drug Administration (FDA) in March 2015. The FDA granted Shire a priority review a month later, and requested additional clinical data, which were supplied in January 2016; approval was granted on 11 July 2016. Lifitegrast was approved by Health Canada in January 2018, and available in Canadian pharmacies as of March 2018.
